Forecast Discussion

Today’s Average Regional Forecast Numbers

Temperatures will vary based on cloud cover and precipitation.  Keep that in mind.

Monitoring the risk of thunderstorms.

Good morning!

It feels like Groundhog Day, the movie!

We have another hot and muggy day ahead of us.   The atmosphere will be moderately unstable.

This morning’s MCS has been tracking through Kansas, Oklahoma, Missouri, and Arkansas.  A tad too far south for most of my forecast area.  Portions of southern Missouri have received much needed rain.

Here is this morning’s infrared Satellite vide of the MCS/thunderstorm complex.

That system will continue to push south southeast through the morning hours.

Outflow boundaries will push into our region through the morning and afternoon.  Those boundaries will likely be areas where new thunderstorms may form.

Some of those storms could produce high wind gusts, small hail, heavy rain, and frequent lightning.

I can’t rule out a severe thunderstorm warning or two today into tomorrow.

Tonight, another MCS is forecast to form over western Missouri and track east southeast.  How far southeast will be key to our rain chances.  We will need to monitor it.

A cold front will enter the region tomorrow.  This front will provide additional chances of showers and thunderstorms.  Again, some could be locally heavy.

Today’s excessive rainfall outlook shows our region in a level one risk of flash flooding.  The lowest level.  Any issues would be isolated.

Saturday, we are in a level one and two risk of flash flooding.

You can see how the level two risk, in yellow, curves to the southeast.  That is where the MCS/thunderstorm complex may track.  Thus, the level two risk.

As has been the case, over the past six weeks, rainfall totals will vary greatly.  From none in some areas to over two inches in other locations.  It is luck of the draw for your location.  It just depends on where the thunderstorms form in this soupy air-mass.

Sunday and Monday will deliver mostly sunny sky conditions.  Just a small 10% to 20% chance of showers and thunderstorms.  It should be dry over most of the region.

I am watching Tuesday/Tuesday night/Wednesday morning  as a warm front moves across our region.  This will be the focus for showers and heavy thunderstorms.  Models are not currently in agreement as to where this will occur.  The odds have been favoring southeast Illinois into Kentucky.  It is possible this occurs outside my forecast area.  For now, I continue to monitor trends in the model guidance.  I will know more over the coming days.

The heat ridge, in the southwest United States that has been making headlines, will push into our region briefly Wednesday and Thursday.

That will replace our northwest jet stream flow.

You can see today’s map shows northwest flow over our region today and tomorrow.  See how the black lines curve southeastward?

Northwest flow brings us thunderstorm chances.  The heat ridge does not.

Then, next Wednesday night and Thursday, notice how the red colors move back into our region.  That is the heat ridge.

That only lasts a couple of days.

Notice what happens by late next week.  The northwest flow returns with more thunderstorm chances.

That is good news for those needing rain.  Which is most of us.

The new drought monitor maps have been posted.

Portions of our region are now in a level two drought.  That is considered severe drought.

Portions of central Missouri are in exceptional (level four) drought.

Last week’s drought monitor compared to this weeks.

Some areas have worsened.

This outlook covers southeast Missouri, southern Illinois, western Kentucky, and far northwest Tennessee.

Today through April 18th:  A couple of the Saturday afternoon and night thunderstorms could produce damaging wind and hail.  The tornado risk is low, but not zero.  Mainly over Missouri for the tornado risk.  The line will weaken with time as it moves farther east.

 

.

Today’s Storm Prediction Center’s Severe Weather Outlook

Light green is where thunderstorms may occur but should be below severe levels.

Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.

One is the lowest risk. Five is the highest risk.

A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
